The Gold Standard of Healthcare Data
The General Practice Research Database (GPRD) is the world's largest database of anonymised longitudinal medical records from primary care linked with other datasets. Containing comprehensive observational data from real-life clinical practice, it provides analytical insight for a wide range of applications in clinical trials, drug safety, outcomes research, clinical epidemiology and genetic research.
